Timeline of cervical cancer

This is a timeline of cervical cancer, describing especially major discoveries and advances in treatment of the disease.

Big picture

Year/periodKey developments
19th centuryCervical cancer is identified as a sexually transmitted disease. At the end of the century, surgery is introduced for treating the disease.
Early 20th centuryEpidemiologists discover that cervical cancer is common in female sex workers and also common in women whose husbands have a high number of sexual partners or were regular customers of prostitutes.[1]
1920sPapanikolaou develops his eponymous technique. The colposcope is developed.
1940sPap smear screening begins.
1980sFirst concrete evidence that specific Human Papillomavirus (HPV) types are linked to cervical cancer.[1] Tobacco use is linked to cervical cancer.
2000sFirst Human papilloma virus (HPV) vaccine is released. Several nations introduce the vaccination, such as United States, Canada, Australia and Japan.[1]
Recent yearsToday, cervical cancer is both the fourth-most common cause of cancer and the fourth-most common cause of death from cancer in women.[2] In 2012, approximately 528,000 cases of cervical cancer occurred, with 266,000 deaths.[2] This is about 8% of the total cases and total deaths from cancer.[3] About 70% of cervical cancers occur in developing countries.[2]

Year/periodType of eventEventLocation
400 BCEDevelopmentFirst description of cervical cancer by Hippocrates.[1]
1834DiscoveryCervical cancer is identified as a sexually transmitted disease.[4]
1842DiscoveryItalian epidemiologist Domenico Rigoni-Stern notices that cervical carcinoma occurs only in married women.[4]
1898DevelopmentAustrian gynecologist Ernst Wertheim describes the operation of radical hysterectomy including removal of the parametrium and pelvic lymph nodes. A few years later, the Wertheim-Meigs operation is introduced as a surgical procedure for the treatment of cervical cancer performed by way of an abdominal incision.[5]
1925DevelopmentGerman gynecologist Hans Hinselmann first describes the foundation of the colposcope, a device used to examine the cervix, vagina and vulva for signs of disease.[6]
1928DevelopmentGreek cytopathologist Georgios Papanikolaou develops a cervical cytology smear test (today called Pap smear) to detect cancer cells. This test will save thousands of lives and help reduce cervical cancer mortality by a wide margin.[7]
1943DevelopmentThe Pap test is first generalized as a procedure, enabling doctors to detect and begin treating cervical cancer before it has a chance to spread.[8] Over the following decades, the Pap test is credited with driving down cervical cancer death rates in developed countries.[9]
1946DevelopmentAylesbury spatula, a wooden spatula with an extended tip, is introduced to scrape the cervix, collecting the sample for the Pap smear.[10]
1951DevelopmentFirst successful in-vitro cell line, HeLa, is derived from biopsy of cervical cancer of Henrietta Lacks.[11]United States
1953DiscoveryAdenocarcinoma in situ (AIS) of the uterine cervix is first described.[12]
1983DiscoveryTeam led by German virologists Harald Zur Hausen and Lutz Gissmann identify HPV 16 in precursor lesions of genital cancer.[1]
1984DiscoveryCigarette smoking is found to increase risk of cervical cancer.[13]
1985DiscoveryHarald Zur Hausen and Lutz Gissmann demonstrate the presence of HPV DNA in cervical cancer cells. These findings create the basis for subsequent studies leading to the development of preventive vaccines.[1]
1988DevelopmentThe Bethesda system (TBS) is introduced as a system for reporting cervical or vaginal cytologic diagnoses. It is considered to be an important achievement in the standardization of screening results.[1]
1989DiscoveryVilloglandular adenocarcinoma of the cervix (a rare type of cervical cancer) is first described.[14]
1989DevelopmentLoop electrosurgical excision procedure (LEEP), which is performed in the surgical treatment of cervical intraepithelial neoplasia, is first described.[15]
1990PolicyThe Breast and Cervical Cancer Mortality Prevention Act is launched, providing nationwide access to free or low-cost breast and cervical cancer screenings to underserved women.[9]United States
1996–1999DevelopmentUnited States FDA approves two new liquid-based Pap tests. In these tests the swab is placed into a special preservative solution, instead of smearing a swab of cervical cells on a slide as in the conventional tests. Compared to the traditional method, these liquid tests provide a clearer, easier to read sample for pathologists to review under a microscope.[9]United States
1998DevelopmentResearchers begin human testing of a possible vaccine to prevent cervical cancer.[16]United States
1999DiscoveryStudy shows that widespread screening reduces cases of advanced cervical cancer in older women.[17]California, US
1999The United States National Cancer Institute issues an alert recommending chemotherapy radiation combination for invasive cervical cancer (cancer that has spread within the cervix or pelvis). This is based on trials showing that women live longer when treated with both radiation and chemotherapy, compared to those treated with the prior standard of radiation or surgery alone.[9]United States
1999DevelopmentDNA test is approved to detect human papillomavirus (HPV), the virus that causes cervical cancer.[18]
2006TreatmentUnited States FDA approves Gardasil, a vaccine that prevents infection with the two high-risk strains of human papillomavirus (HPV) known to cause about 70 percent of cervical cancers. Gardasil is approved for girls and young women aged 9 to 26.[9]United States
2007DiscoveryStudy suggests that the act of performing a Pap smear produces an inflammatory cytokine response, which may initiate immunologic clearance of HPV, thus reducing the risk of cervical cancer.[19]South Africa
2008DiscoveryResearchers discover that two minimally invasive techniques, laparoscopic and robotic radical hysterectomy (removal of the uterus) with radical pelvic lymphadenectomy (removal of surrounding pelvic lymph nodes) are as effective as traditional radical hysterectomy and lymphadenectomy in women with cervical cancer.[9]
2009DiscoveryHPV vaccine Gardasil is found to be over 90 percent effective in preventing cervical cancer in women aged 24 to 45 who received all three vaccine doses, and who are not infected by the virus.[9]
2010PolicyYoung women in Japan become eligible to receive cervical cancer vaccination for free. However, in 2013 the local Health Ministry withdraws the vaccine recommendation for girls due to several hundred adverse reactions to the vaccines reported.[20]Japan
2013DiscoveryAdding targeted drug bevacizumab (Avastin) to standard chemotherapy is found to improve survival for patients with relapsed and advanced cervical cancers.[9]
